Chaotic scattering in open Hamiltonian systems is an important topic
in nonlinear science due to its fundamental applications in
classical [1]}, [2]}, [3]} and quantum physics
[4]}, [5]}, [6]}. This phenomenon is also relevant in a wide
variety of fields such as chemistry [7]}, [8]}, biology
[9]}, [10]} and even medicine [11]}. Most of the
work in chaotic scattering has been made by using purely
conservative systems
[12]}, [13]}, [14]}, [15]}. However, almost
every system in nature is influenced by its surrounding environment.
For that reason, recently some research has considered perturbations
in the conservative systems as an attempt to model the coupling of
the system with the environment. In particular, the effects of
dissipation [16]}, [17]}, [18]}, periodic forcing
[19]}, [20]} and noise [21]}, [22]}, [23]}, [24]} have been considered. It has been shown that weak
dissipation can convert the Kolmogorov-Arnold-Moser (KAM) islands
into attractors, and that the periodic forcing can destroy the KAM
structures at the same time that it decreases the unpredictability of
the system [20]}.
